Rumbling when cruising
Hello,
My 70 c-20 is making a rumbling noise. At first it was occurring when going about 55+ mph and not that noticeable. Gradually getting worse. I can feel it in steering wheel. Would this be some kind of bearing? Serge

Re: Rumbling when cruising
I'd be changing those bearings , Can you feel it when turning or does it get worse ?
On the lighter side I usually try to get that Rumbling sound going down the road ![]()

Any thoughts on carrier bearing. I had that replaced couple years ago with a 15$ one form Truck Shop catalog. Good point on rumbling sound.

Yeah, I'd be pulling those hubs asap and check them bearings before they "Weld"them selves to your spindles, that's a monster you don't want, trust me.
New bearings/seals/re-pack with a good high temperature wheel bearing grease, better to do it all at the same time. Ben ![]() |

I had same problem . Checked rear end , drive shaft . Never could figure out problem , until front center cap fell off . Bearing was shredded .

Re: Rumbling when cruising
Okay! I guess it's time to learn about replacing and repacking wheel bearings.
Is this something a novice can attempt or should I go to a professional? Thanks for your time.
